we have been in afghanistan for 11 years in iraq 8, 9. we have a lot of political problems in this region but we have other things we need to worry about economic issues, jobs economy right here at home. as a foreign policy realist you have to say if they cross some particular deadline there is not a reason for us to get involved it's not something that rises to the level that we should be getting involved. >> we talk about red lines as it relates to iran and that crisis. you wonder where the red line involves here. the president said even if they move chemical weapons others said if they use chemical weapons. where is it? >> the use of chemical weapons. on the other side the rebels if you see an allegiance to al qaeda we have seen a hint to that. remember the up rising is sunni led and al qaeda is on the sunni side of things. you have challenges about who is going to come out ahead of it. the u.s. doesn't want to have fingerprints on a situation where we have empowered and emboldened people with an iron fist. look at iraq over the weeken
